Re: Basic Integration

Integrating (0,3) gives me 3.

Re: Basic Integration

Hi;


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.

Re: Basic Integration

x dx integrates to 1/2 x^2

Now, plugin 3 to x, that will do as the constant will cancel out

Am I right bobbym?

Re: Basic Integration

Thanks bobbym. Agnishom, you are doing integration before differentiation?!

Re: Basic Integration

Nope, I know differentiation also.

But I have not done much practise

Re: Basic Integration

Hi Agnishom;

Am I right bobbym?

You are close, you have left out the constant 2 / 3.

Re: Basic Integration

Yes your book helped, thanks!

But the truth is that My father was explaining me the concept since last three or four years

Re: Basic Integration

Yes, sorry!
I actually didn't forget the constant. I just thought it isn't important to mention it. As it is obvious

Yes, I tested my IQ once through an online test. It says something like 140 or 160 (which ever was called 'gifted', can't remember the exact value)

Are online tests reliable?

Re: Basic Integration

They are if you get high results! If they agree with me I consider them reliable.

Re: Basic Integration

Okay, for you I will tell.

When I tested it caused a stir. The colonel who was conducting the tests said either I was darn near a genius or I was slightly smarter than an apple. They could not figure which was true so they tested me again. This chart explains the results:

Bonzo the chimp
Bertha the chimp
Busby the chimp
Beyonce - Rihanna - Spears a tie!
Paris Hilton
lemur
bobbym
apple
combined IQ's of the US senate
a pear
a peach pit
amoeba

My parents and teachers were outraged, they shook their fists at him and threatened to disembowel him. But he brought soldiers with him that escorted him out safely. Everyone tried to comfort me, do not listen to him they said, we all know you are a genius and will accomplish great things. Yea, in their dreams.

Re: Basic Integration

At my age, I no longer care about Jungian tests of my original head. The sharpening, permanently doubled my intellectual capacity.

Re: Basic Integration

I guess my IQ is 145.
I took a test one year ago, and another one today.
The first one says 146 and the second one says 145

Re: Basic Integration

I would believe that. According to your picture you have a nice round head. When you sharpen it you will really soar.

142 for me. But online tests are not too secure. One of them told me I have an IQ of 652.

That is a nice IQ to have. That is pretty close to Yoda's.
